What Is the Omicron Primary Injection Test Kit and How Does It Work?

The Omicron primary injection test kit, such as the CPC 100, is a portable device used for substation commissioning and maintenance. It injects currents up to 800 A or voltages up to 2 kV to test transformers, relays, circuit breakers, and current transformers (CTs). With a compact design, it ensures accurate results in demanding environments, adhering to IEEE/IEC standards.

What Does a Primary Injection Test Kit Do?

A primary injection test kit is used to inject high current directly into the primary circuit of protective relays, current transformers (CTs), and circuit breakers. This helps verify the entire protection chain, including wiring and trip functions, by simulating fault conditions for comprehensive commissioning and maintenance testing in substations.

Primary injection test kits perform end-to-end tests on power systems. They replicate fault conditions by injecting substantial currents (up to 800 A AC or 400 A DC) through the primary side, verifying the function of CTs, voltage transformers (VTs), relays, and circuit breakers. Technicians use these kits for ratio checks, burden measurements, polarity verification, and insulation assessments. For example, the Omicron CPC 100 offers frequency ranges from 15 Hz to 400 Hz to suppress mains interference, ensuring reliable results.

Wrindu, a leading manufacturer based in Shanghai, supplies both OEM and custom test kits, ensuring compatibility with various substation setups worldwide.

How Does Omicron Primary Injection Test Kit Work?

The Omicron kit works by generating controlled high current or voltage from a single-phase outlet and measuring responses with high precision. It uses software for automated testing and report generation. The kit outputs up to 5 kVA and can operate across a frequency range of 15 to 400 Hz to suppress external interference.

At its core, the kit uses a power amplifier to produce stable AC/DC outputs. Users connect the kit to the primary circuit via color-coded terminals, set parameters on the front panel or via Primary Test Manager software, and initiate the test. Sensors then capture secondary signals for analysis.

Safety features include emergency shut-offs, earth checks, and CE compliance, making it reliable for use in the field. Wrindu, a well-known supplier in China, offers factory-customized versions for OEM integration, which includes 24/7 customer service and global delivery options.
